PROBLEM TO BE SOLVED: To provide a variable power optical system having excellent optical performance, an optical device having the variable power optical system, and a method for manufacturing the variable power optical system.SOLUTION: A variable power optical system ZL comprises, in order from an object side: a first lens group G1 having positive refractive power; a second lens group G2 having negative refractive power; a third lens group G3 having positive refractive power; a fourth lens group G4 having positive refractive power; a fifth lens group G5 having negative refractive power; and a sixth lens group G6 having positive refractive power. When varying power from a wide angle end to a telephoto end, the distance between the first lens group G1 and the second lens group G2 changes, the distance between the second lens group G2 and the third lens group G3 changes, the distance between the third lens group G3 and the fourth lens group G4 changes, the distance between the fourth lens group G4 and the fifth lens group G5 changes, and the distance between the fifth lens group G5 and the sixth lens group G6 changes. |
